Author: Daniel S. Karls, University of Minnesota (karl0100 |AT| umn DOT edu) Date: 8/04/2014 This Test uses the Test Driver to compute the cohesive energy of a fcc lattice of Magnesium atoms at a variety of lattice spacings ranging from 0.8*a_0 to 1.5*a_0. The value of "a_0" (as it is referred to in the Test Driver) passed to the Test Driver is taken to be the equilibrium lattice constant for the Model being used, as obtained by querying the KIM database for Test Results from the LatticeConstantCubicEnergy_fcc_Mg Test when paired against the relevant Model.
